Description
The HP 8753C provides excellent RF network measurements for the lab and production test areas. When combined with a test set, it provides a complete solution for characterizing the linear behavior of either active or passive networks, devices, or components from 300 kHz to 6 GHz. With two independent display channels available, you can simultaneously measure and view the reflection and transmission characteristics of the device under test in overlay or split screen for-mat on the crisp color display. The easy-to-use softkey selection of measurement functions allows you to measure the magnitude, phase, or group delay characteristics of your device’under test. The test sequence function allows rapid and consistent execution of complex repetitive tests with a single keystroke. In sequencing mode, you make the measurement once from the front panel and the instru-ment “learns” the keystrokes so no additional programming expertise is required. You can even set other HP-IB instruments via a test se-quence. Other productivity enhancements include a plot/print buffer, limit testing, arbitrary frequency testing, and marker tracking func-tions. Finally, segmented calibration and interpolative error correc-tion allow you to apply vector accuracy enhancement over a subset of the frequency range that you initially calibrated the HP 8753C. The HP 8753C’s integrated synthesized source provides > 100 mW of output power, 1 Hz frequency resolution, and linear, log, list, pow-er, and CW sweep types. Three tuned, 300 kHz to 3 GHz (Option 006 – extends to 6 GHz) receivers allow versatile independent power mea-surements or simultaneous ratio measurements over a 100 dB dynam-ic range. By employing the HP 85047A Test Set with the HP 8753C, the reflection and transmission characteristics of the device under test can be investigated from 300 kHz to 3 GHz or from 3 MHz to 6 GHz with the test set’s frequency doubler enabled.
Non-linear Device Testing Non-linear device characterization is possible with the HP 8753C. Swept 2nd and 3rd harmonic levels of an amplifier can be displayed directly or relative to the fundamental carrier (dBc) when employing the optional harmonic measurement capability (Option 002). Ampli-fier harmonics up to 40 dBc can be measured quickly and convenient-ly on a swept-frequency basis for fundamental signals as low as 16 MHz, using the same test configuration used to measure gain. Power meter calibration provides a leveled absolute power to devices that are sensitive to absolute input or output levels. The HP 8753C automati-cally controls an HP 436A, 437B, or 438A Power Meter to set the power anywhere in the test configuration with power meter accuracy. The HP 8753C has the capability to perform mixer tracking and conversion loss measurements. These are possible because the HP 8753C’s tuned receiver can be offset from it’s synthesized source by the LO frequency of the mixer. Time Domain Analysis Time domain responses can be displayed by the HP 8753C with Option 010. The instrument computes the Inverse Fourier Transform of the frequency domain data to display the reflection or transmission coefficient versus time. The HP 8753C offers two time domain modes. The Low Pass mode provides the traditional Time Domain Reflec-tometer (TDR) measurement capability and gives the response of the network to a mathematically simulated step or impulse response. This mode gives information of the type of impedance (R, L, C) at the discontinuity. The Band Pass time domain mode, which has only the impulse stimulus, has no frequency restrictions and provides the time domain response of frequency selective devices such as SAW filters or antennas. Gating may be used to selectively isolate a single response to view the frequency domain response of individual portions of a component without disturbing the circuit itself.
